Description

HOUSEHOLD REFRIGERATOR AND METHOD FOR VENTILATING ONE

REFRIGERATOR CONTAINERS

The invention relates to a household cooling device with at least one cooling compartment and a container which can be accommodated in the cooling compartment with a lower part for receiving refrigerated goods and a lid which can be covered over the lower part, the container having at least one air passage opening. The invention also relates to a method for ventilating a container accommodated in a cooling compartment of a domestic cooling device. The invention is particularly advantageously applicable to refrigerators with at least one cooling compartment, the temperature and / or humidity of which can be adjusted

WO 2018/227662 A1 discloses a humidity control device for a refrigerator and a method for humidity control for a refrigerator. The moisture regulating device comprises a storage room for receiving food; a humidity detection device for detecting humidity in the storage room; and a humidity mode controller for determining a humidity control mode from a plurality of humidity control modes and controlling the humidity in the storage room using the selected humidity control mode. In particular, the relative humidity in a storage room for vegetables and food to be stored dry ("vegetable compartment") can be regulated by a fan in the ceiling. For this, humidity sensors of the humidity detection device are required inside and outside the storage room. Since the air flowing around is also used to cool the refrigerator (at approx. 5 ° C), it is not the temperature of the house that is regulated, but only its humidity. When the fan is switched off, the relative humidity in the vegetable compartment is comparable to the surrounding refrigerator. When storing vegetables or other highly moist foodstuffs, the relative humidity in the compartment initially increases, but then decreases over time due to the removal of the humidity via a "fan inlet and outlet air opening" The disadvantage of this is firstly the use of expensive humidity sensors and secondly the lack of temperature control in the storage room. The relative humidity is also linked to the "constant" refrigerator air and is therefore very limited in its setting options . DE 102012209937 A1 discloses a refrigeration device, in particular a household refrigeration device, which has a storage space for items to be cooled, at least one passage for the inflow and / or outflow of air to and from the storage space being formed in a wall delimiting the storage space. The passage can be closed by a movable closure element. A fan for driving an air flow is arranged in the storage room and can be operated when the passage is closed.

JP 2009 121803 A discloses a refrigerator / freezer comprising: a heat insulating box body; a vegetable chamber which is disposed in the heat insulation box body and accommodates food; a cold air circuit in communication with the interior of the vegetable chamber; a vegetable chamber temperature sensor for detecting the temperature in the vegetable chamber; a vegetable chamber humidity sensor for detecting humidity in the vegetable chamber; an outside air introducing part for transmitting air from the heat insulating box body to the interior of the vegetable chamber; and a control part. The control part is controllably constructed to control the drive of the outside air introduction part on the basis of the humidity in the vegetable chamber, which is detected by the vegetable chamber humidity sensor, and to stop the drive of the outside air introduction part when a temperature in the vegetable chamber is reached that is not lower than the predetermined temperature.

It is the object of the present invention to at least partially overcome the disadvantages of the prior art and, in particular, to provide an improved option for storing items to be cooled, for example food, in a household refrigerator.

This object is achieved according to the features of the independent claims. Advantageous embodiments are the subject of the dependent claims, the description and the drawings.

The object is achieved by a household refrigerator, having at least one cooling compartment and a container that can be accommodated or stowed in the cooling compartment for receiving items to be cooled, wherein the container has at least one air inlet opening and at least one air outlet opening spaced therefrom as well as an air flow setting device, the household refrigerator also has a controllable air flow setting device and is set up to set a volume flow from the cooling compartment by setting at least one setting parameter of the air flow setting device to vary the air flow entering the container through the at least one air inlet opening between at least two values.

In this way, the advantage is achieved that an air stream flowing through the container can be generated in the cooling compartment independently of a climate (including a temperature and an air humidity). In other words, the relative humidity and the temperature in the cooling compartment on the one hand and the air speed over the goods stored in the container on the other hand can be decoupled from one another. This makes use of the fact that, by means of the air flow adjustment device, a strength of the air flow or a size of the volume flow of the air passed through the container can be set or varied in a targeted manner.

This air flow can advantageously be used to adjust the temperature and the humidity in the container to the - typically predetermined - temperature and humidity of the cooling compartment. The adaptation of the climate is brought about, for example, by preventing the formation of noticeable temperature gradients through the air flow generated. The formation of an air layer with increased moisture in the area of water evaporating is also prevented.

In addition, the advantage is achieved that by varying the air volume flow, the dehumidification rates of the refrigerated goods can be varied even at a given humidity and / or temperature in the refrigerated compartment, which can lead to improved storage of the refrigerated goods. For example, refrigerated goods accommodated in the container can be stored in at least two different ways, e.g. with different dehumidification levels.

Another advantage is that an adaptation of the container climate in the area of the goods to be cooled to the climate in the refrigerated compartment can be implemented particularly quickly. It is also an advantage that the above functionalities can be implemented in the container without dedicated or additional sensors. This is because the air flow adjustment device only influences the volume flow of the air passing through the container. The dependence of the volume flow on the at least one setting parameter of the air flow setting device can, however, easily be determined experimentally and / or by flow calculations and, for example, stored in a control device, for example as a characteristic curve or family of characteristics.

The air flow in the container is not an air flow circulating in the container, but an air flow entering from the cooling compartment through the at least one air inlet opening, then flowing through the container and subsequently exiting the at least one air outlet opening back into the cooling compartment. The volume flow of the air flow entering the container through the air inlet opening corresponds at least approximately (possibly except for small leakage losses, e.g. through gaps between the cover and the lower part) to the volume flow of the air flow flowing through the container and the volume flow of the air flow emerging from the at least one air outlet opening .

The household refrigerator can be a refrigerator, freezer, or any combination thereof. The household refrigerator can have one or more cooling compartments, for which in particular a respective climate (including an associated temperature and / or relative humidity) can be set. The cooling device can also be referred to as a refrigeration device.

The associated container can be seen to accommodate different types of refrigerated goods, for example different types of food such as vegetables, fruit, cheese, meat products, etc. In particular, a container has a - eg schalenför miges - lower part for receiving the refrigerated goods and a the lower part of the cover that can be covered. The lower parts can also be referred to as “baskets”. At least the lower part of the loading container can be pulled out of the cooling compartment, in particular it can be completely removed.

It is an advantageous further development for generating an air stream flowing through the container in a large volume that the container is at least largely sealed off from the cooling compartment apart from the at least one air inlet opening and the at least one air outlet opening. In one variant, the lid can simply be placed on the part rest.

The air flow adjustment device can be controlled, for example, by means of a control device of the household refrigerator. It can be electrically movable, e.g. by means of an electric motor.

In order to enable an air flow within the container to be particularly effectively overflowing, it is an advantageous development that the at least one air inlet opening and the at least one air outlet opening are present in opposite areas of the container, e.g. on a front area and a rear area of the container, in particular within a front third to a quarter or a back third to a quarter of the container.

It is a further development that at least one air inlet opening and at least one air outlet opening are located in the lid of the container. It is a further development that at least one air inlet opening and at least one air outlet opening are located in the lower part of the container, e.g. in a front wall and in a rear wall of the lower part. However, mixed forms are also possible in which, for example, at least one air inlet opening or at least one air outlet opening is located in the lower part and at least one air outlet opening or at least one air inlet opening is located in the cover, etc. The at least one air outlet opening can also be at least one in the lower part include existing air outlet opening and at least one air outlet opening in the cover, etc.

The air flow adjusting device can in particular be arranged on the at least one air inlet opening, e.g. in the air inlet opening or covering the at least one air inlet opening on the inside or outside.

It is an embodiment that the air flow adjustment device is attached to the container. As a result, a particularly compact design can be achieved with low air flow losses. The air flow adjustment device can be arranged, for example, on the lid or on the lower part of the container.

It is an embodiment that the air flow adjustment device is attached to the lid and the lid is attached in the cooling compartment. This has the advantage that - e.g. at Pulling out and pushing in the container - only the lower part is moved while the lid remains stationary in the cooling compartment. As a result, in turn, a power supply for an air flow adjusting device arranged on the cover can be provided in a particularly simple and reliable manner by means of electrical cables. If, on the other hand, the air flow setting device is moved along with the container, its power supply can be achieved, for example, via electrical cables, in particular spiral cables, electrical plug-in contacts, electrical surface contacts, inductive voltage transmission, etc.

In one embodiment, the air flow adjustment device is arranged outside the container in such a way that it is positioned opposite the at least one air inlet opening when the container is inserted into the cooling compartment. In this way, too, a power supply for the air flow adjustment device can be provided in a particularly simple and reliable manner by means of electrical cables, even if the at least one air inlet opening is located in a movable part of the container, e.g. the lower part. The air flow adjustment device is in particular arranged in a stationary manner in the cooling compartment. When the container is inserted, the air flow adjustment device can be separated from that of the at least one air inlet opening by a gap. In order to avoid noticeable air loss, when the container is in place, it can be placed on the container, e.g. on the edge. It can be provided with a seal for this purpose.

In one embodiment, the air flow adjusting device has a motor-driven, variable-speed fan ("container fan"). Its speed corresponds to the setting parameter. This has the advantage that, due to the known speed-dependent fan power, a precisely adjustable air volume flow through the container can be generated, which can also be decoupled particularly easily from the climate in the cooling compartment. In addition, a particularly strong air flow can advantageously be generated through the container in this way. When using a container fan, the further advantage is achieved that it can also be arranged at the at least one air outlet opening when its suction side faces the container interior.

In one embodiment, an evaporator of a heat pump and a variable-speed fan ("evaporator fan") for distributing air flowing over the evaporator in the cooling compartment are assigned to the cooling compartment. By such, basically be known arrangement, the temperature and the humidity in the refrigerator compartment adjust specifically. If, for example, a low humidity (e.g. 30% r.h.) is desired for a cooling compartment temperature, e.g. by a user or automatically, this can be achieved by setting an evaporator temperature on the evaporator that is noticeably lower than that on the device side Cooling compartment temperature while the speed of the evaporator fan is set to a low value. The evaporator fan can then even be operated clocked. If, on the other hand, a higher humidity is desired (e.g. 80% r. F.), this can be achieved by setting an evaporator temperature on the device side only slightly lower than the cooling compartment temperature, but the speed of the evaporator fan is set to a high value is set. With a given temperature and humidity in the cooling compartment, the air flow generated by the evaporator fan in the cooling compartment, which flows around the container from the outside in order to cool it, is therefore also given. A further development is that the cooling compartment temperature is specified (for example, it is set at 5 ° C), while the relative humidity can be set by the user or by a program.

If a container fan is provided, the air flow in the container can be adjusted independently of the air flow generated by the evaporator fan in the cooling compartment. Furthermore, there is the advantage that a position of the at least one air inlet opening, and thus also of the container fan, can be arranged at basically any point on the container, in particular regardless of whether the at least one air inlet opening is in an air flow area of the evaporator fan with ho or not.

It is an advantageous embodiment when there is an arrangement with an evaporator fan that the at least one air inlet opening is located in an air flow area generated by the evaporator fan with high air speed and the air flow adjustment device has a movable cover element, by means of which a volume flow through the at least one air inlet opening inflowing air is adjustable. This has the advantage that a container fan can be dispensed with, since the air flow flowing through the container can be branched off from the cooling compartment air flow generated by means of the evaporator fan. The cover element is therefore intended to control the incoming volume flow through targeted adjustment of the effective flow cross-section of the at least one air inlet opening vary. In other words, the cover element can be moved in such a way that it can adjust the ratio of air flow penetrating into the container to the total air flow generated by the evaporator fan. If the volume flow generated by the evaporator fan is known, the volume flow flowing into the container can also be set with sufficient accuracy by setting the position of the cover element (and thus the flow cross-section). The cover element can be moved by an electric motor for example.

A further development which is advantageous for enabling a large volume flow through the container is that the at least one air inlet opening is located on one side of the container on which the evaporator fan is also arranged. This can, for example, be a rear wall of the lower part of the container if the evaporator fan is arranged on a rear wall of the cooling compartment.

When using the movable cover element, the strength of the volume flow through the container is dependent on the speed of the evaporator fan, which in turn is dependent on the set humidity of the cooling compartment. There - z. B. by experiments or calculations - the dependency of the volume flow through the container on the set humidity of the refrigerator compartment and / or directly on the speed of the evaporator is known, the volume flow through the container can be adapted to the set humidity. For this purpose, a table or a family of characteristics can be used, for example, with one of the characteristics for a certain humidity of the cooling compartment or speed of the evaporator fan indicating a plot of the volume flow as a function of the position of the cover element. With a higher humidity / speed of the evaporator fan, a smaller cross section of the at least one air inlet opening tends to be released than at a lower humidity / speed in order to set the same volume flow through the container.

It is a further development that the cover element is an element that can be pivoted laterally over the at least one air inlet opening, for example in the form of a slide. The pivoting movement can be a rotary movement or a linear movement. It is a further development that the cover element is an element that can be rotated about a body axis, for example in the form of a flap. A setting parameter can, for example, be a position of the Cover element or a position of the associated drive motor include or be.

It is a further development that of the at least two different volume flows that can be set by the air flow adjustment device, at least one volume flow is in the range from 1 to 3 m ³ / h. This rather low value is particularly suitable for adapting the climate in the container to the climate in the cooling compartment, while a dehumidifying effect due to the air flowing through is small to negligibly small. This development is particularly advantageous for storing items to be cooled that should not dry out, for example fruit and vegetables, especially leafy vegetables.

It is an embodiment that of the at least two different volume flows which can be set by the air flow setting device, at least one volume flow is at least 8 m ³ / h. This has the advantage that, in addition to adapting to the climate of the refrigerated compartment, noticeable dehumidification of the refrigerated items can be effected. This development, which can also be referred to as "active dehumidification", is particularly advantageous for the storage of refrigerated goods that are to be stored dry in order to preserve their quality, for example tea leaves or baked goods. Furthermore, if desired, refrigerated items can be dried, e.g. fruit. In these two applications in particular, it is advantageous if the humidity in the cooling compartment is set to a low level.

In addition, the advantage can be achieved that the refrigerated goods can be adapted particularly quickly to the climate of the refrigerated compartment. This allows warm refrigerated goods (e.g. food that is still warm) to be cooled down particularly quickly to the temperature of the refrigerator compartment and / or frozen refrigerated goods to be raised to the temperature of the refrigerator compartment particularly quickly for thawing.

The volume flow of at least 8 m ³ / h can correspond to a maximum adjustable volume flow.

In one embodiment, the household refrigerator is set up to set values of the at least one setting parameter as a function of the program or mode. The air flow adjustment device can thus be used in a particularly user-friendly manner for treating the items to be cooled which are accommodated in the container. The cooling mode, also known as ok

The cooling program can be viewed, for example, can be selected or activated by the user. For example, a user can - for example via a user interface of the household refrigerator or remotely via an application program ("app") - specify the program or mode in which the refrigerator compartment is operated with the container inserted therein. For example, two or more of the following modes can be selected: a first mode ("normal mode" or "equilibrium mode"), in which the comparatively low volume flow is generated, for example in the range of, for example, 1 to 3 m ³ / h. This is particularly suitable for setting or maintaining an equilibrium moisture content of a stored product in which neither humidification nor dehumidification is desired; a second mode ("dehumidification mode"), in which a comparatively high volume flow rate is generated, for example of 8 m ³ / h or higher. The dehumidification mode is carried out in particular until the user switches to another mode; at least one third mode ("defrosting mode" or "rapid cooling mode"), in which a comparatively high volume flow is generated, for example of 8 m ³ / h or higher. This mode can be activated, for example, for a certain period of time (for example 15 or 30 minutes) until it is automatically switched to another mode, for example normal mode. Alternatively or additionally, it is possible to switch to the other mode in an event-controlled manner, for example after it has been established by means of a temperature sensor that the temperature prevailing in the cooling compartment is within a predetermined temperature range. The thawing mode and the rapid cooling mode can be configured the same or different.

In addition, in a further development, a fourth mode ("humidity mode") can be set in which the air flow setting device is set so that the lowest possible volume flow is generated through the container, advantageously a practically negligible volume flow. This achieves the advantage that, due to the evaporation of water through the goods to be cooled, even higher humidity can be achieved in the container than in the cold room, especially in the vicinity of the goods to be cooled. This development can be implemented in that the container fan is switched off or the cover element covers the at least one air inlet opening as completely as possible. One embodiment is that the household refrigerator is set up to automatically adjust the air flow setting device after detection of a door opening process in such a way that a higher volume flow is generated in the container. This is based on the consideration that typically after a door is opened, moisture is carried into the household refrigerator (and thus also into the refrigerator compartment), which can lead to a loss of quality in foods with a low water content (e.g. baked goods such as biscuits). Increased performance of the container fan can remove this moisture more quickly and / or reverse a partial moisture absorption that has already taken place.

It is a development that the household refrigerator is set up to automatically increase the volume flow (eg analogous to the third mode) for a certain period of time (eg 5 or 10 min) remains activated until automatically or event-controlled in the previously set mode is switched back, e.g. to normal mode.

It is a further development that the household refrigerator is set up to automatically increase the volume flow only if one or more specific modes were previously activated. For example, in a further development, the automatic increase in the volume flow can be started or carried out when the first mode is active. In a further development, the automatic increase in the volume flow cannot be carried out when the fourth mode is active. Furthermore, in a further development, the automatic increase in the volume flow does not need to be carried out when the third mode is active, since a high volume flow of the air flowing through the container is already generated in the third mode.

The object is also achieved by a method for ventilating a container housed in a cooling compartment of a household refrigerator, which has at least one air inlet opening and at least one air outlet opening spaced therefrom and wherein in the method a flow volume or volume flow of one from the cooling compartment through the at least an air flow flowing into the container is adjusted by varying an adjustment parameter of an air flow adjusting device associated with the at least one air inlet opening. The method can be designed analogously to the household refrigerator and has the same advantages. The properties, features and advantages of this invention described above and the manner in which they are achieved will become clearer and more clearly understood in connection with the following schematic description of an exemplary embodiment which is explained in more detail in connection with the drawings.

Household refrigerator with a container inserted in a cooling compartment according to a third embodiment.

1 shows a sectional side view of a section of a household refrigerator in the form of a refrigerator 1 with a container 3 inserted in a cooling compartment 2 (eg for vegetables). The container 3 comprises a bowl-shaped lower part 4 and a lid 5. The refrigerator 1 can also have further cooling compartments 6, 7, which are separated from the cooling compartment by a respective thermally insulated partition 8. The container 3 can be pulled out of the cooling compartment 2 after opening a front door 9. Instead of the door 9, there can be a cover wall that is permanently connected to the lower part 4 (not shown), which can have a handle shell, for example.

At a back of the refrigerator compartment, an evaporator 10 of a heat pump of the refrigerator 1 and a variable-speed evaporator fan 11 are available. When the evaporator fan 11 is in operation, it blows compartment air FL to be cooled (indicated by dashed lines) onto the evaporator 10, the then cooled compartment air FL being distributed in the cooling compartment 2 and thereby sweeping around the container 2 on the outside. So the walls of the container 2 and thus also its interior are cooled. In the present case it is assumed by way of example that the compartment temperature of the cooling compartment 2 is permanently set to 5 ° C., for example is regulated. A temperature sensor that may be used for this purpose is not shown. In contrast, the relative humidity in the cooling compartment 2 can be set by setting the temperature of the evaporator 10 and the speed of the evaporator fan 11. The lower the relative humidity should be, the cooler the evaporator 10 is set and the lower the speed of the evaporator fan 11 is set. The setting of the relative humidity can be programmed, for example, or set directly by a user.

As also shown in Figure 2, there is an air inlet opening 12 in the lid 5 of the container 3, in which an air flow adjustment device in the form of a container fan 13 is used, as well as an air outlet opening 14 spaced therefrom a slot-shaped air inlet opening 14 are shown, the distance, number and shape of the openings 12, 14 can be chosen as desired. In addition, the container fan 13 can be placed on the min least one air inlet opening 12 from the outside or from the inside.

The speed of the container fan 13 can be adjusted by means of a control device (not shown) of the refrigerator 1. When the container fan 13 is in operation, this compartment air FL blows through the air inlet opening 12 into the container 3, which exits through the air inlet opening 14 and into the cooling compartment 2. As a result, an air flow LS is generated in the container 3 (as indicated by the thick arrows), the flow volume or volume flow of which can be adjusted via the speed of the container fan 13. The container fan 13 can be designed so that it can generate a volume flow of the air flow LS of up to 8 m ³ / h or even more.

The container fan 13 can be operated, for example, in at least two modes that can be selected, for example, by the user or by program control, for example from the group comprising a "normal mode" or "equilibrium mode", a "dehumidification mode", a "thawing mode", a "rapid cooling mode" and a "humidity mode". In the normal mode, the volume flow is set to a value between 1 and 3 m ³ / h, whereby fruit and vegetables placed in the container 3 retain their moisture and are therefore dehumidified or humidified.

In the dehumidifying mode, the volume flow is set to 8 m ³ / h or more, whereby fruit placed in the container 3 is dehumidified or dried.

In the thawing mode, the volume flow is set to 8 m ³ / h or more for a limited period of time, as a result of which frozen goods placed in the container 3 are thawed more quickly. The defrost mode can be activated by the user or can be activated automatically, e.g. if it is recognized that a compartment temperature has dropped noticeably.

In the rapid cooling mode, the volume flow is set to 8 m ³ / h or more for a limited period of time, as a result of which warm goods placed in the container 3 are cooled more quickly. The defrost mode can be activated by the user or can be activated automatically, for example if it is recognized that a compartment temperature rises noticeably.

The refrigerator 1 can also be set up to automatically adjust the air flow setting device after detection of a door opening process so that a higher volume flow of the compartment air FL in the container 2 is generated for a limited period of time.

3 shows a sectional view in side view of a detail from a household refrigerator in the form of a refrigerator 15 with a container 17 inserted in the refrigerator compartment 16. The refrigerator 15 is constructed similarly to the refrigerator 1, but the lid 5 is now firmly in place via fastening elements 18 the cooling compartment 16 is arranged. When the container 17 is pulled out, only the lower part 4 is pulled out, while the lid 5 remains in the cooling compartment 16. This facilitates an electrical connection of the container fan 13.

4 shows a sectional side view of a section of a household refrigerator in the form of a refrigerator 19 with a container 21 inserted in a cooling compartment 20. The refrigerator 19 is constructed similarly to the refrigerator 1, but with the at least one air inlet opening 12 in a rear wall of the Lower part 22 of the container 20 is introduced and a cover element 23 is used as an air flow adjusting device. The cover 24 only has the air outlet opening 14.

Here the evaporator fan 11 is set up in such a way that it blows specialist air FL with a high volume flow or with a high air speed onto the air inlet opening 12. The air inlet opening 12 can be covered in different proportions by the cover element 23, so that an effective flow cross-section for the compartment air FL can be set by means of the cover element 23. This in turn allows the size of the volume flow flowing through the container 21 to be adjusted, in particular also taking into account the speed of the evaporator fan 11.

The cover element 23 can, for example, as indicated by the double arrow, be a slide or a flap. Its position can be adjusted by means of a servomotor (not shown). The cover element 23 can be attached to the lower part 22 of the container 20 or can be arranged in a stationary manner in the cooling compartment 20.

5 shows a sectional side view of a section of a household refrigerator in the form of a refrigerator 25 with a container 27 inserted in a cooling compartment 26. The refrigerator 25 is constructed similarly to the refrigerator 19, but a container fan 13 is now used as the air flow adjustment device will. The container fan 13 covers from the outside at least one air inlet opening 12 made in a rear wall of the lower part 28 of the container 27. The air inlet opening 12 and the container fan 13 are advantageously arranged in an area of the cooling compartment 26 with a low air flow of the compartment air FL, since such an influence of the speed of the evaporator fan 11 on the volume flow of the air flow LS within the container 27 can be kept low.

The container fan 13 can be attached to the lower part 28 of the container 20 or can be arranged in a stationary manner in the cooling compartment 20.

In general, "a", "a" etc. can be understood as a singular or a plurality, in particular in the sense of "at least one" or "one or more" etc., as long as this is not explicitly excluded, for example by the expression " exactly one "etc. List of reference symbols
